means whereby the working parts of the pumps will not be clogged up through accu- 'mulation of solid matter.

Another object of this invention is to provide, in a pump of this kind, means for outting solid particles prior to entrance of the articles into the pump mechanism.

A further object of this invention is to provide a readily portable'pump ofthis land in which allcheck valve members found in numerous pumps have been eliminated.

The above and various other objects and advantages of this invention will in part be described in, andin part be understood from the following detailed description of the present preferred embodiment, the same being illustrated inthe accompanying drawin 5, wherein igure 1 is a detail front elevation of a pump constructed according to the preferred embodiment of this invention;

Figure 2 is a vertical sectional view taken 'on the line 22 of Figure 1;

Figure 3 is a sectional view taken on the line 33 of Figure 2;

a Figure 4 isa sectional view taken on the line 44 of Figure 2; 1 Figure 5 is a sectional view taken on the line 5-5 of Figure 2, and

Figure 6 is a detail plan view of one of the lifting elements used in the pump. 1

Referring to the drawings, wherein like numerals of reference designate corresponding parts throughout the several views, the numeral 10 designates generally a pump casing or housing comprising a pair of elongated tubular members 11 and 11 which have their 5 abutting wall portions cut away so as to provide a substantially unitary housing structure of tubular construction. The housing or casing 10 is provided adjacent the upper end thereof with an outlet spout 12, and the lower end 13 of the housing is preferably passupwardly through the housing 15 and the upper end of the housing 10 so as open as at 13, so as topermit the liquids to 10. Disposed longitudinally through the tubular section 11 is a pump shaft 14 which at the lower end thereof is rotatablymountedin a 5 transversely disposed bearing 15 which is mounted in the lower end of the housing 10.] The upper end of the shaft 14 extends through a cap or head 15, and a pulley 16 is secured tothe upper end of the shaft 14.,the pulley being adapted to receive a belt or be otherwise connected to a power member for rotation thereof. The cap15 comprises a top plate 1? having downwardly extending flanges 18 engaging about the outer surface of the housing members 11 and 11, and a lug 19 is secured to each side of the housing 10- adjacent the upper end thereof for threadably receiving a bolt member20 which extendsthrough a securing bar 21. a This securing bar 21 is adapted. to remov ably secure the head or cap 15 on the upper end of the housing 10. A gasket 22 is inter posed between the inner surface ,of thercap 1 to effectively seal the cap within the housing. A second shaft 23 is disposed within. the other tubular member 11' and is rotatably mounted at the lower end thereof in the. transversely disposed bearing 15 carried by the lower end of the housing 10 and the upa per end of the shaft 23 extends through the head or cap 15. A gear24 is mounted-on the upper endof the shaft 23 andnieshess with adrive gear 25 mounted onithe'drive shaft 14. In this manner, the sh'aft23 will rotate reversely fromthe shaft 14.

A' plurality of water lifting members or propellers generally designated as 26 are secured to the drive shaft 14 at spaced intervals therealong, these water lifting members or propellers 26 comprising a hub section 27C which engages about the periphery of the shaft 14 and is secured thereto by means of a securing pin 28 or the like. A. plurality of. spirally disposed bladesj29 aresecuredto the hub 27 and the outer edges of these blades 29 extend closely adjacent the innersurface of the tubular member 11. The lower edge of each blade '29 is preferably. disposed in a having a slight pitch so as to cooperate withthe propeller blades 29 in raising water or the like in the tube 11. The shaft 23 is also provided with a plurality of lifting members 26-havingblades 29 secured to the hub sec-' These blades 29 are so arranged tions 2 with-respect to the blades 29 that the blades willoverlap 'a'slightdistance, the lifting members26'being mounted onthe shaft 23 in such position that the blades 29" are slightly iiradvance of the blades29. In this manner," the synchronization of the two blades is obtained so that any heavy articles the like which are drawn upwardly throi'iglr'the tube sections 11 and 11 Will not adhere to'tlie' blades 29 and 29 inasmuch as one bl ade'wi llcoact to remove the material from the blade on the other lifting member. 3 n'like manner, a second cutter member 31 isn'iounted onthe shaft 23, the blades 33 of which are' mounted at substantially right angles 'to the blades 33 of the cuttermem ber- 31 Theseblades also cooperate with the blades 33, in notonly cutting the solidparticle's drawn through the'housing 10, but

also :in' removing the materialadhering to the-opposing blades; As shown in Figure 2,9t1ie shafts 14 and'-23 "ar'e provided with roller be'arings35 and a packing gland mem bei 36 is adapted to seal the roller bearings 85in the"bearingsupport15.

In theoperation of this device, the pulley 16 inay be connected to a suitable power *member by means of a beltorthe likqso as'to rotatef'the drive" shaft 14, at a relatively ra'pid*-rate',' which rotation*will also rotatethe driven shaft 23 'reversely but atthe same a'te as' the drive shaft 14. The 'lowerend offthehousing 10 may be projected into the desired liquid'and upon rotation of the liftmg members '26and 26'with the shafts 14" and 23,=-==respect-ively, the liquids together with any'relatively solid matter will be forced upwardly through the tubular sections 11-'-- and 11 and -forced outwardly through the spout-'12. While 'tlie'spout 12 isfnrounte d'on the tubular 'se'ction'll I do not wish' to be limited to this construction as, if desired, the spout 12 may be connected to eitherjoffthe.tubular sections or disposed intermediate thereof and in communication withf 'each housing: 7 a g M It "1s, of course, understood that various ii changes andmodlficatlons may be made in the details of construction and design of the above specifically described embodiment of this invention without departing from the spirit thereof, such changes and modifications being restricted only by the scope of the following claim.

What is claimed is a j A pumpof the character described comprising in combination, a housing having an open lower end, a pair of shafts rotatably mounted inthe housing in spaced parallel relation to each other, gears carried by each shaft whereby to rotate one shaft reversely from-the other, an outlet spout secured to the housing, a plurality of spaced interengaging spirally disposed liquid lifting blades mounted onsaid shafts, and cutter members carried by each of said shafts'adjacent' 'one end thereof and 'in spaced"relati0n to the lowermostblade-whereby to cut articles being drawn through'the housing by the blades.

In testimony whereof I hereunto afiiX my signature.
